Table 9 Downstream I/O Devices DIP Switch and Jumper Settings
Note:
If a NX4IN is not required in a system, start addressing the NX4OUT at
DIP switch 3. If a NX4IN is configured with an address other than 1 or 2, the
MPA2 panel will not communicate with it. Likewise, if a NX4OUT is
configured with an address other than 3 through 6, the MPA2 panel will not
communicate with it.
The MPA2 board is not intended to provide either module power or module
output load power for downstream I/O. A separate 24 VDC supply should
be used to provide power to all downstream modules and output loads.
